There is alot to consider when buying a lift. Are you going off-road? Do you have a winch, heavier bumper, rear rack with attachments? Depending on these answers, will determine what kit you need.
Rubicon Express and BDS make a great kit for heavier rigs. Superlift makes a good lift for lighter rig. And if this kit will only be for looks and little off-road, Rancho makes a godd add-a-leaf kit, which will net you about 2.5 inches.
You should get more advice from this forum, so good luck.
